摘要: 杭州望朝中心為各立面均呈連續(xù)傾斜凹凸的特殊體型建筑,結(jié)構(gòu)設(shè)計(jì)時(shí),為滿足立面及室內(nèi)空間的使用要求,結(jié)構(gòu)構(gòu)件需最小化。 對(duì)該項(xiàng)目的基礎(chǔ)形式和結(jié)構(gòu)體系進(jìn)行了介紹,因按照相關(guān)規(guī)范無法準(zhǔn)確選定結(jié)構(gòu)的體型系數(shù),故設(shè)計(jì)了風(fēng)洞試驗(yàn),對(duì)立面及體型優(yōu)化帶給風(fēng)荷載的影響進(jìn)行了研究。 從多遇地震下結(jié)構(gòu)受力性能、中震下樓板有限元應(yīng)力、大震下的動(dòng)力彈塑性、超限高層建筑的加強(qiáng)設(shè)計(jì)及空間連續(xù)斜柱外框架優(yōu)越的抗側(cè)力貢獻(xiàn)五個(gè)方面,對(duì)本工程進(jìn)行了抗震設(shè)計(jì)。 對(duì)結(jié)構(gòu)的構(gòu)件內(nèi)力進(jìn)行了施工模擬分析,探討了分層加載和一次性加載對(duì)構(gòu)件內(nèi)力的影響。 研究結(jié)果表明:采用沿豎向高度改變平面寬度、周邊切角、各立面連續(xù)傾斜凹凸的措施,可減小結(jié)構(gòu)風(fēng)致響應(yīng) 30%;沿建筑周邊布置空間連續(xù)斜柱鋼框架,可有效減小混凝土核心筒尺寸;采用部分樓層樓板滯后施工的工藝,可有效降低轉(zhuǎn)換桁架的內(nèi)力并優(yōu)化構(gòu)件截面。

Abstract: Hangzhou Wangchao Center is a special shape building with continuous inclined concave convex of each facade.In the structure design, in order to meet the use requirements of facades and indoor space, the structural components shouldbe minimized. The basic form and structural system of the project were introduced,the wind tunnel test was designed due tothe shape coefficient of the structure cannot be accurately selected according to the relevant specification, and the influenceof the facade and shape optimization on the wind load was studied. The aseismic design of the project was carried out fromfive aspects: the mechanical performance of the structure under frequent earthquake, the finite element stress of the floorunder moderate earthquake, the dynamic elastoplasticity under large earthquake, the strengthening design of transfinitehigh-rise buildings and the superior lateral force contribution of the spatial continuous inclined column outer frame. Theconstruction simulation analysis of the internal force of the components of the structure was carried out, and the influence oflayered loading and one-time loading on the internal force of the components was discussed. The results show that thewind-induced response of the structure can be reduced by 30% by changing the plane width along the vertical height, theperipheral tangent angle and the continuous inclined concave convex of each facade; spatial continuous inclined columnsteel frame was arranged around the building, which can effectively reduce the size of concrete core tube; the internal forceof the transfer truss can be effectively reduced and the section of the component can be optimized by adopting the technologyof lagging construction of some floor slabs.

Keywords: wind-induced response; wind tunnel test; lateral force; space continuous inclined column steel frame;construction simulation analysis; lag construction technology of some floor
